1. An inkjet recording apparatus comprising:
an image forming section configured to eject ink onto a sheet in which first to M-th regions are defined, M being an integer of at least 2;
a heater including first to M-th heat sources and configured to heat an n-th region among the first to M-th regions of the sheet using an n-th heat source among the first to M-th heat sources, n being an integer of at least 1 and no greater than M;
a first calculation section configured to calculate an ink ejection amount to the n-th region, the ink ejection amount to the n-th region being an amount of ink to be ejected to the n-th region;
storage that stores therein heating information that corresponds to the ink ejection amount to the n-th region and that indicates whether it is necessary to heat the n-th region;
a determination section configured to determinate whether or not to cause the n-th heat source to generate heat based on the heating information and the ink ejection amount to the n-th region calculated by the first calculation section;
a controller configured to control the n-th heat source; and
a second calculation section, wherein
the heating information contains temperature information indicating a first heating temperature for the n-th region of the sheet,
the first heating temperature for the n-th region of the sheet is set according to the ink ejection amount to the n-th region thereof,
the second calculation section calculates a second heating temperature of the n-th heat source based on the temperature information and the ink ejection amount to the n-th region of the sheet calculated by the first calculation section,
when the determination section determines not to cause the n-th heat source to generate heat, the controller controls the n-th heat source not to generate heat, and
when the determination section determines to cause the n-th heat source to generate heat, the controller controls the n-th heat source to generate heat at the second heating temperature for the n-th heat source.
